This is a wicked cool experiment that we created on our own during class.
You should try this experiment on your own time, it's dope.
Purpose: To see if different salts make ice melter faster or slower.

DV : Melting time
Hypothesis: The rock salt will melt first. Then the epsom salt will melt. Then Table Salt, Sand, and the no salt ice.
Procedures:
1.Get out five beakers and fill them with ice cubes.
2. Fill each beaker with 5 grams of each salt (each salt goes in different beaker)
3. After 5 minutes, record what you see. Measure how much water was lost in a graduated cylinder. Do this a couple times.
4. Make a table of which ice melted the fastest and slowest.
5. When you are done, clean up.

How To Heat A Liquid Lab wuddup graph.bmp Mhm, that's our graph. Check it out kids.
We conducted an experiement with boiling water. We ran the lab for 10 minutes and every 30 seconds recorded the temperature. The temperature started aat 19.0 degress celsius. As the lab went on the test tube got foggy and the water started bubbling. We learned that when water reaches it's boiling point, it doesn't increase by much after that. The boiling point for water is 100 degrees celsius.

Summary:
As the volume of the air in the syringe increases the pressure decreases. If you look at the table you can see this. The pressure of each numer like 5 decresed when we pushed on it. So this proves tht as the volume increases the pressure decreases.
10/29/07 Solid
Solids are the state in which matter has a definite shape and volume. The two types of solids are crystalline and amorphous. The particles in a crystalline solid have an orderly arrangement, whereas the particles in an amorphous solid do not have an orderly arrangement it is more scattered. This pen is a solid because it has a definite shape and volume.

The floating boat displaces about 10grams of water. This is because the mass of clay was about 10grams. The reason the boats floated was because of the thin walls and the curved inside. So with the thin walls and a curved inside the boat will displace about 10grams of water. The sinking boats have less than the amount of 10grams of water, this averages to 6.23grams of displaced water. So the mass of the water depends on the mass of the clay.

The data shows no correlation. In one case the mass was greater than the volume out of everything for the medal rod. The spacer though, had a bigger volume for the class than the volume. This shows that there is no correlation in our data.
10/4/07 Hypothesis: The boat sunk because it filled up with water and sunk to the bottom of Lake Beaker. The other boat is afloat because there’s no water inside it and it is stuck to the wall.
Mass: The amount of matter that something is made of. The boat is made out of clay
and the heaviness of the boat might have sunk it. The basic SI unit of mass is in
kilograms. Also mass makes up all matter, and is measured with a balance.
Volume: The amount of space that something occupies or the amount of space that
something contains. Volume of a cube is side x side x side. Prism is area of base x
height. Volume measures in cubic^3.
Weight: The measure of the gravitational force exerted on an object. The gravitational force is not only from Earth, but from the Moon and other planets too. The bigger the planet or star the more gravitational force is exerted. The SI unit of weight is the newton.
Malleability: The ability of a substance to be pounded into thin sheets. These items are malleable lead, copper, and tin. These items are somewhat malleble silicon, antimony,and boron. None of the nonmetals are malleble.Somemetals though are malleble.
Texture: Sensations caused by the external surface of objects recived through the sense of touch. The things that have texture can be smooth, rough, spikey, and other kinds of surfaces.
Color: Color derives from the spectrum of light. Different colors are red, orange, yellow, green, blue, purple, pink, white, brown, black, and many other different colors. Color is associated with every object.
Ductility: The ability of a substance to be drawn or pulled into a wire. Like malleability the same items are ductility like lead, cooper, tin. Also some have some ductility like silicon, antimony, and boron, most metals are ductile. The properties of ductility (and malleability) describe a metal's ability to be reshaped.
Inertia: The tendency of all objects to resist any change in motion. An object with a small mass has less inertia than an object with a large mass. This makes it harder to push a car rather than push a bicycle.
Solubility: The ability to disolve in another substance;
